CCS/TMS320C6748: UIA Sysem Analyser takes too much of processor's time

Tool/software: Code Composer Studio

Hello,

I'm working with Blackhawk USB 560 v2 System Trace debugger and transferring log data using UIA system analyser in runtime mode.

I used the article https://e2e.ti.com/support/development_tools/code_composer_studio/f/81/p/614025/2262772#2262772 to make it work.

But unfortunately it seems that it eats to much of the processor's resources. When I open Rtos Analyser -> Printf and Error logs or Load Analysis while the project of voice exchange from/to codec is running, CPU load reaches up to 100% and some gaps in speech in the output occur. If I change LoggingSetup.loggerType from LoggingSetup.LoggerType_JTAGRUNMODE to LoggingSetup.LoggerType_STOPMODE all the gaps disappear and CPU load on "CPU Load: graph" decreases to 70-80 %.

Is it possible to decrease CPU load in run-time mode?

Best regards,

Egor.

Can you attach your .cfg file and let us know what version of SYS/BIOS and UIA you are using?

Hi Egor,

Sorry for the delay,

Can you remove LoggerBuf from the .cfg? System Analyzer does not work with LoggerBuf records. Please have the records go into the loggers managed by the LoggingSetup module.
